Different results same query

Win XP Pro, Office 2003 pro

I created an Access query using the query grid to read an ODBC database: SQL
WHERE as follows:

WHERE (((GL_BILLING_ENTRIES_DETAIL.GL_DET_GL) In
("11511250","11561260","11511251","11561261","1151 1230","11561255","11511245","11561275")))

The query returns records with a GL_DET_GL other than those listed in the
"IN()" clause.

Converting to a SQL Specific - Pass through Query, however, and changing
the Double-quotes (") to Single-quotes (') in the sql string yields the
correct list of records containing only the requested GL Numbers!

How is that possible and how do I ensure my ODBC queries run locally will
return the correct records?
